Animation of Hurricane Katrina Sea Surface Temperatures from AMSR-E
(courtesy of NASA/Goddard Space Flight Center Scientific Visualization Studio)

This visualization shows the cold water trail left by Hurricane Katrina. The data is from August 23 through 30, 2005. The colors on the ocean represent the sea surface temperatures, and satellite images of the hurricane clouds are laid over the temperatures to clearly show the hurricane positions. Orange and red depict regions that are 82 degrees F and higher, where the ocean is warm enough for hurricanes to form. Hurricane winds are sustained by the heat energy of the ocean, so the ocean is cooled as the hurricane passes and the energy is extracted to power the winds. The sea surface temperatures are 3-day moving averages based on the AMSR-E instrument on the Aqua satellite, while the cloud images were taken by the Imager on the GOES-12 satellite.

 

Data Products

For each EOS instrument, there exists a suite of EOS standard data products. Each EOS instrument science team develops, validates, and maintains the alogrithms and science software that produces their instrument's EOS standard data products. The AMSR-E Level 1 products will be generated by JAXA and distributed to the AMSR-E Science Investigator-led Processing System (SIPS) located at Remoted Sensing Systems for processing to level 2A Resampled Brightness Temperatures. These are then forwarded to the Global Hydrology Resource Center SIPS for processing of EOS Level 2B and 3 standard products. The Level 2 and 3 products conform to EOSDIS standards for science data and metadata. These products, metadata, and associated documentation will be archived and distributed by the Snow and Ice Distributed Active Archive (DAAC) at the National Snow and Ice Data Center. )
